iPad vs iPad 2, speed of PDFs?


Technology


Wife is using "my" Ipad more and more, meaning I get to use it less and less. Plus half of its capacity is now used to store Sex and the City videos.

Anyway, if I break down and get an iPad 2, will page turning in pdfs be any faster?

Part of my wants to wait until a new Nook Color is out and root it, but then again Jason said at Kublacon that the Pathfinder iPad apps would be out "very soon".


The side by side reviews put the iPad 2 is a tad faster at PDF rendering. A good chunk of that has to do with reader App used (personally I'd avoid iBooks), and (no surprise) the increase in internal RAM. I don't have an iPad 1 to compare with personally but I can generally thumb through a Paizo image heavy PDF at a decent speed. The extra RAM lets it get ahead of my reading and queue up the next page or two. What I like more is that Safari isn't constantly having to reload pages as I switch between them. Oh it still does do it from time to time, but not nearly as often as it does on my 3rd Gen iPod Touch.

Here is an article put out by the guys who make iAnnotate PDF reader and annotation software.

I have no timeline on when a Nook Color 2 will be out, or what it will change so I can't give you an answer about Wait or Buy.

There is already a company that deals with "very soon". It's called Valve Time. Coming "Soon" could be two more months. If it gets released before iOS 5 ships for the public I'll be happily surprised.

According to reviews the iPad 2 is faster than the iPad but you pay a premium for it.
I use good reader on an iPad 1. Speed is good and I can not complain. I bought my iPad after iPad 2 came out and saved a bucket load!

Great link! Thanks!


I actually don't use iAnnotate myself. I use GoodReader. Aji left the iPhone/iPod app in the dust with nary a word so I'm still POed at them. I find GoodReader to be a near essential App for many reasons beyond just it's PDF reading functions.

@Maskia, I wouldn't exactly call it a premium as you're playing the same price as when the original iPad came out. Now what you do pay a premium for is any unit passed the based 16 GB. Apple has higher profit margins on the 32 and 64 GB devices,,, of which I paid XD.

*edit*

Well, what do you know. GoodReader finally gets "recently viewed" Tabs.

Yeah, the last update of GoodReader is kind of amazing. Between the tabs and better gesture response, I'm really pleased.


Has anyone seen a significant boost in performance going from 16MB to 32MB or more memory? This would be based on using a single application at a time.

Yeah - great update! The tabs are going to be very useful!

I'm not sure what your talking about? If you mean the storage memory at 16 GB, 32 GB, and 64 GB that doesn't really impact overall performance. The only thing that gets you is less shuffling of data on and off the device. I rarely *need* to sync my iPad 2 64GB or iPod Touch 3rd Gen 64GB with my computer, I do sometimes when I want to do a backup or update a large number of Apps across both devices, but normally they don't connect by USB to my computer very often.

If you mean the increase in RAM from 256 MB to 512 MB check this out. Now that's not to say it won't ever need reload the page. If you browse expensively in a different tab it will eventually drop the tabs to free space. There is a old and still valid take on what's important in computer, RAM, get as much as you can. This is becoming less of an issue with Solid State Drives, but RAM can still make or break your experience. Doesn't matter how fast the processor is if it can't access data in timely fashion. Personally I would have like a Gig of RAM, but may have been to much to wish for. 768 would have been nice. Even 640. I think you get the point, more RAM = better.

Also keep in mind the iPad 2 has a SGX543MP2 GPU, which combined with OpenCL gives the iPad 2 even more umph over the iPad 1 then you'd expect. Developers can send various tasks to the GPU instead of to the A5. That SGX543MP2 GPU is the main reason why we'll be getting real time video mirroring over AirPlay with iOS 5 on the iPad 2.

What I still find disturbing is my iPad 2 is almost functionally superior to my 1.67 GHz G4 PowerBook which I got back in 2003 for college. It defiantly blows it away on battery life.


Actually, you helped address some of my concerns, as I plan on buying the entry level model for iPad2. Basically to read some PDFs, and perform some basic web searching or word processing.
